STEAM-RADIATOR.

SPEGIFICATlION forming part of Letters Patent No. 231,722, dated August31, 1880.

Application filed December 22, 1879.

To all whom it may concern:

Be it known that I, THADDEUS O. J or, of

Titusville, in the county of Crawford and State of Pennsylvania, haveinvented a new and Improved Steam Heater or Radiator; and I do herebydeclare that thefollowin g is a full, clear, and exact description ofthe same, reference beinghad to the accompanying drawings, formin g partof this specification, in which- Figure 1 is a top view of a radiator orheater consisting of a single segment of hollow heatdistributing wingsor projections, a steam-receiving chamber, an air-valve, and inlet andoutlet valves, the same being constructed in accordance with myinvention. Fig. 2 is a back view of the same. Fig. 3 is a verticalradial section of the same in the line 00 a: of

Fig. 1, and Fig. 4 is a vertical transverse section of the same in theline y y of Fig. 1. Fig. 5 is a top view of my improved radiator asshown in Fig. 1, but consisting of two segments similar to that shown inFig. 1. Fig. 6 is a front view of the plan of segmental radiator shownin Fig. 1, but showing three segments, one arranged vertically uponanother; and Fig. 7 is a vertical section of the pile of segmentalradiators shown in Fig. 6, the section being in line 3 y of Fig. 5.

The nature of my invention consists, first, in a steam-receiving andcondensed-water-discharging chamber formed with hollow closed extensionswhich are in communication with its interior and present broad taperingsides internally and externally, and are gradually widened from theirinner to their outer ends in both horizontal and vertical planes, aspresently described, whereby a very compact radiator with very greatheating capacity is produced at comparatively small cost, and theappearance of which is very tasteful; second, in a radiator or heaterhaving its inlet-valve for steam and its outlet-valve for condensedwater coupled together by a novel combination of devices, whereby theopening of the two valves and the closing of the same simultaneously areeffected by the one means, and thus the opening of either of the saidvalves or the closing of the same without opening or closing its fellowvalve is rendered impossible and serious accidents are avoided; third,in the combination of two or more segmental ra diators arranged on thesame horizontalplane and not in communication with one another, and twoor more segmental radiators arranged on the same horizontal plane withone another, but on a different horizontal plane from the first seriesof radiators, the respective piles of segmental radiators not being incommunication withone another, and the wings of one radiator extendingbetween the wings of another, as will be hereinafter explained; fourth,in the segmental radiators provided with peculiar means for forming thejoint connections and securing the radiators together, as will behereinafter explained; fifth, in a novel combination and arrangement oftwo or more series of segmental radiators, the radiators of each seriesconsisting, respectively, of a steam-receiving chamber and extensionwings which are hollow, the radiators of each series communicating withone another, the hollow Wings of one radiator projecting between thewings of another radiator, as will be hereinafter explained; sixth, in aradiator comprising a series of horizontal segments each of which has asteam-chamber and hollow radiating wings, and is provided with itsindependent steaminlet pipe and valve and outlet pipe and valve andair-escape valve, as will be hereinafter explained.

A in the accompanying drawings represents one segmental heater orradiator constructed in accordance with my invention. The chamber a,into which the steam is first conducted, is formed of two segmentalplates, 00, set vertically, two horizontal segmental plates, d 01,forming the bottom and top, and two radial end plates, 0 c. It may be inseparate pieces or it may be cast all in one piece. In the bottom plate,d, inlet and outlet pipe collars b bare provided, and upon these collarsrespect ivcly are applied pipes for admitting steam and conveying awaythe water of condensation. On the upper ends of the collars b b flaringvalve-seats are formed, and in the top plate, (1/, stuffing-boxes f fare fitted by being connected to hollow collars g g, and through thesestuffing-boxes valve-rods h h are passed downward and their lower endsmade to fitinto and close the inlet and outlet valve passages.

Both of the valve-rods h h are connected together by a strap-plate, t,which acts similarly to a bow-spring when the valves on the rods are tobe opened by it, and as a rigid bar when the valves are to be closed byit. The strap-plate i is passed under a stand, j,-and is acted upon by athumb set-screw, 7a, which is fitted to work up and down in a nut, is,of the stand. The lower end of the screw is coupled by a shoulder andcollar to the strap-plate, and by this means the plateis raised andlowered by the screw. By turning the screw to the right both valves areclosed at the same time, and by turning the screw to the left bothvalves are opened simultaneously, Thus itis impossible to open one valveor close one valt e independently of its fellow valve. The spring actionof the strap-plateinsuresasudden opening of both valves when thepressure of the screw is released sufficiently. However, the screw andstrap-plate are mainly depended upon for opening the valves.

From the outer segmental plate, 0, hollow extensions 1 are provided.These extensions communicate with the chamber a, and they are radialwith reference to the center of the segmental plates 0 c, as shown. Thebottom lines of the extensions 1 are horizontal, while the top lines areoblique or inclined in an up- Ward direction from the top plate, d, ofthe chamber a to the termini of the extensions. The top surface, as wellas the bottom, of the extensions presents the form of a very acuteangle, while the cross-section of each extension is in either a lozengeor diamond or other analogous form. Theinner ends of the extensions arerectangular in shape, while their outer ends are in form of a diamond;and said ends may be made with a proper bulge or convexcurved form. Atthe middle of the inner'segmental plate, 0, bolting-flanges m are formedon the back edges of the horizontal top and bottom plates, d cl, throughwhich bolts 0 for coupling several segmental sections together arepassed when the heater is formed of several segmental sections piled oneupon another.

When'the heater is formed of several segmental sections, as in Fig. 6,those sections which are on a lower plane than the top section areprovided with short flanged joint collars n, with joint-stems n, thestems fitting steam-tight into holes a formed in the bottom plates, d,of the respective sections, and if necessary packing'rin gs may beplaced around the stems upon the collars. The screw-bolts 0, which passthrough the flanges, are provided With heads on one of their ends, andnuts 0 on their other ends, and by screwing up the nuts the sections arebound together, and the joints at a a n which form the communicationsbetween the several sections, or allow the steam to circulate throughoutthe several sections, are made steam-tight.

When a heater or radiator is formed of segmental sections placed againstone another, either singly, as in Fig. 5, or in piles of three, more orless, as shown in Fig. 6, the plan view of the heater will be ahalf-circle, and by adding another segmental heater or a pile ofsegmental heaters the plan view will be a threequarter circle, and byadding another segmental heater or a pile of segmental heaters the planview will be a complete circle in general design.

The valve-rods with conical valves on their ends will be the same inconstruction and operation for a pile of segmental heaters as they arefor a single segmental heater, except that the rods are required to bemade long enough to extend from the top heater to the bottom one.

When the heaters are piled one upon another the wings of one heateroccupy a position opposite the spaces between the wings of anotherheater, and those portions of the hollow extensions or wings of oneheater which rise upward 011 an oblique line from the top plate of thesteam receiving and distributing chamber a extend up between the wingsof another heater in the manner illustrated in the drawings, Fig. 6. Bythis means the heater can be made with a large amount ofheating-surface, and yet not be of great height.

The form of the extensions or hollow wings I is such that the air to beheated rising between them is caused to pass first through passageswhich gradually decrease in width, and then through passages whichgradually increase in width, and then in passages which, 9

in like manner, decrease and increase in width, and so on until itescapes at the top of the pile of radiators or heaters.

The peculiar ,form and arrangement of the extensions or wings are suchthat the air-spaces are divided in such a manner that intersectingdiagonal circulation-ways are formed, as will be seen by referring toFig. 6 of the drawin gs, and by this means the air is more exposed tothe surfaces heated by the steam in its course through the pile ofradiators.

In carrying out my invention on a large scale the form of the wings orextensions Z, and also of the steam-chamber a, as described, will befound the most effective and desirable; but I do not confine myself tothe precise form and arrangement shown, as these may be changed invarious equivalent ways without departing from the invention which isshown and described.

The advantage of the segmental form shown in Fig. 1 is that it willstand diagonally across a corner of a room and leave an air-space behindit, between itself and the wall. The same benefit of an air-circulationspace between the heater and the wall is secured when the heaters arearranged against the side of a Wall in a half-circle, and when theheaters are arranged to form a complete circle an air-circulation spaceis formed centrally of the pile of heaters or radiators.

Each segmental heater has its own supply and escape pipe and air-valve19, and each segmental pile of heaters has its own supply and escapepipe, as well as an air-valve.

The air-valve 19 consists of a long rod with a conical valve end, 19',and with a thumb-button, 19 The valve end is inserted through astuffing-box, q, of one of the extensions or wings I,

IIO

and is forced up to a flaring seat, q, of the steam-chamber, said seathaving an air vent or passage through it, as shown in the drawings. Whenthe valve 1) is adjusted for operation the vent of the seat q is open,and when steam is introduced into the heater or radiator the air isallowed to escape, and this having been accomplished, the heat of thesteam causes the rod to expand or become lengthened enough to close theair-vent and thereby prevent the escape of steam. When the steam is cutoff from the heater the valve cools down and becomes shortened bycontraction, and thereby again opens the air-vent to the same extent aswhen the rod was first adjusted.

111 operating with the radiators steam maybe supplied to one, two, ormore piles of segments, according to the quantity of heat required, aseach pile will be provided with its own let-on and shut-off cock fromthe main steam-supply pipe.

What I claim as my invention is- 1. The segmental radiator comprisinginits construction the steam-receiving chamber a, with the hollowradiating extensions or wings I, which are in communication with theinterior of said chamber, and said radiator being provided with inletand outlet valves, and otherwise constructed and operating substantiallyas herein described.
